Description

Technical Field

[0001] This utility model relates to the technical field of tobacco processing equipment, and in particular to a leaf re-drying machine. Background Technology

[0002] The tobacco leaf threshing and re-drying process involves leaf curing followed by finished product packaging. To improve the purity of the packaged tobacco products and reduce the impact of metal impurities on product quality, a metal detector is usually installed between the leaf curing machine and the packaging equipment. Tobacco leaves containing metal impurities are then manually sorted. However, this sorting process is prone to clogging, and manual sorting is inefficient and yields unsatisfactory results, especially when the mixed metal impurity particles are small, making complete sorting impossible.

[0003] The related technology discloses an automatic metal removal device for tobacco leaf re-drying line, which includes a first conveyor belt and a second conveyor belt with the same conveying direction. An electromagnet is set directly above the first conveyor belt. The tobacco leaves are conveyed on the first conveyor belt. When the tobacco leaves pass under the electromagnet, the electromagnet can adsorb the metal impurities mixed in the tobacco leaves, thereby effectively removing the metal impurities from the tobacco leaves.

[0004] However, the tobacco leaves accumulate in a thick layer above the tobacco curing machine conveyor belt, and metal impurities may be trapped inside the tobacco leaves. The magnetic attraction range of the electromagnet is limited, and it cannot effectively remove the metal impurities trapped inside the tobacco leaves. Moreover, the electromagnet may also attract some tobacco leaves while attracting metal impurities, resulting in waste of tobacco leaves. Utility Model Content

[0005] The purpose of this invention is to provide a leaf re-drying machine to solve the technical problem that the existing automatic metal removal device for leaf re-drying lines cannot effectively remove metal impurities wrapped inside the tobacco leaves and easily causes tobacco waste.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A blade re-drying machine, which includes:

[0008] A conveying mechanism is configured to convey materials, one end of which is a discharge end. The materials are thrown out by the conveying mechanism from the discharge end, and the path through which the materials are thrown out from the discharge end is a first scattering trajectory.

[0009] A guiding mechanism is provided in the scattering area of ​​the first scattering trajectory. The material is scattered onto the guiding mechanism along the first scattering trajectory, and the guiding mechanism changes the scattering path of the material to a second scattering trajectory.

[0010] A magnetic attraction mechanism is disposed within the throwing area of ​​the second throwing trajectory. The magnetic attraction mechanism is used to attract metal impurities in the material and changes the throwing path of the material to a third throwing trajectory.

[0011] Optionally, the magnetic attraction mechanism includes a magnetic attractor and a mounting component. The magnetic attractor is connected to the mounting component, and the mounting component can be connected to an external frame. The angle and installation height of the magnetic attractor relative to the second spraying trajectory are adjustable.

[0012] Optionally, the mounting component is a universal hinge, the universal hinge includes a ball joint, the magnetic component is connected to the ball joint, and the mounting height of the universal hinge on the external frame is adjustable.

[0013] Optionally, the ball joint includes a ball head and a split ball socket. The magnetic attractor is connected to the ball head, and the ball head is movably connected to the split ball socket. An elastic clamping ring is provided on the outer periphery of the split ball socket, which can clamp the split ball socket to lock and limit the ball head.

[0014] Optionally, the guiding mechanism includes a roller and a roller bracket, the roller being rotatably connected to the roller bracket, the roller bracket being connectable to an external frame, and the roller bracket being adjustable in direction and position on the external frame.

[0020] The beneficial effects of this utility model are:

[0021] This invention provides a blade re-drying machine, including a conveying mechanism, a guiding mechanism, and a magnetic attraction mechanism. Material is thrown onto the guiding mechanism via a first throwing trajectory. The guiding mechanism changes the material's throwing path to a second throwing trajectory and disperses the material. The magnetic attraction mechanism is positioned within the throwing area of ​​the second throwing trajectory. The discharge end of the conveying mechanism, the guiding mechanism, and the magnetic attraction mechanism can be integrated, improving the space utilization of the production line. Material is thrown onto the magnetic attraction mechanism via the second throwing trajectory. During the throwing process, the material is dispersed, allowing metal impurities trapped inside the material to detach and be exposed on the surface. The magnetic attraction mechanism can then attract these exposed metal impurities. Compared to directly placing an electromagnet above the material, this blade re-drying machine effectively removes metal impurities trapped inside the material, thus improving the material's purity. During the throwing process, the material and metal impurities naturally separate due to gravity. The magnetic attraction mechanism only attracts the metal impurities, avoiding the absorption of material along with the metal impurities, thereby preventing material waste.

[0025] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0026] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1 As shown, this utility model provides a blade re-drying machine, including a conveying mechanism 1, a guiding mechanism 2, and a magnetic attraction mechanism 3. The conveying mechanism 1 is configured to convey material 100, with one end being a discharge end 11. The material 100 is thrown out of the discharge end 11 by the conveying mechanism 1, and the path of the material 100 thrown out of the discharge end 11 is a first throwing trajectory 200. The guiding mechanism 2 is located within the throwing area of ​​the first throwing trajectory 200. The material 100 is thrown onto the guiding mechanism 2 along the first throwing trajectory 200, and the guiding mechanism 2 changes the throwing path of the material 100 to a second throwing trajectory 300. The magnetic attraction mechanism 3 is located within the throwing area of ​​the second throwing trajectory 300. The magnetic attraction mechanism 3 is used to adsorb metallic impurities in the material 100, and the magnetic attraction mechanism 3 changes the throwing path of the material 100 to a third throwing trajectory 400.

[0030] Specifically, material 100 is thrown onto guide mechanism 2 via first throwing trajectory 200. Guide mechanism 2 changes the throwing path of material 100 to second throwing trajectory 300, and guide mechanism 2 can disperse material 100. Magnetic attraction mechanism 3 is set in the throwing area of ​​second throwing trajectory 300. The discharge end 11 of conveying mechanism 1, guide mechanism 2, and magnetic attraction mechanism 3 can be integrated into a single design, improving the space utilization of the production line. Material 100 is thrown onto magnetic attraction mechanism 3 via second throwing trajectory 300. Material 100 is dispersed during the throwing process, and metal impurities wrapped inside material 100 can detach from material 100 and be exposed on the surface. Magnetic attraction mechanism 3 can attract the exposed metal impurities. Compared to directly placing electromagnets above material 100, the blade re-drying machine provided in this embodiment can effectively remove metal impurities wrapped inside material 100, thereby improving the purity of material 100. During the scattering process, the material 100 and the metal impurities naturally separate due to the difference in gravity. The magnetic attraction mechanism 3 only adsorbs the metal impurities, thus avoiding the waste of material 100 when the magnetic attraction mechanism 3 adsorbs the metal impurities.

[0031] In this embodiment, the conveying mechanism 1 is a conveyor belt, which is horizontally arranged. The material 100 is laid flat on the conveyor belt for conveying. The leaf re-drying machine is equipped with three zones: drying, cooling, and rehumidification. The material 100 passes through the three zones in sequence under the conveyor belt and is then discharged from the discharge end 11. The material 100 can be tobacco leaves or tea leaves, and is not specifically limited here.

[0032] Furthermore, such as Figure 1 As shown, the first throwing trajectory 200 and the second throwing trajectory 300 have opposite throwing directions. This allows the material 100 to be thrown onto the guide mechanism 2 via the first throwing trajectory 200, where it is dispersed, and then returned to the discharge end 11 via the second throwing trajectory 300. The magnetic suction mechanism 3 is located on the second throwing trajectory 300 and is close to the discharge end 11, further improving the space utilization of the production line.

[0033] Optionally, the magnetic suction mechanism 3 includes a magnetic suction component and a mounting component. The magnetic suction component is connected to the mounting component, which can be connected to an external frame. The angle and installation height of the magnetic suction component relative to the second spraying trajectory 300 are adjustable. When the conveying speed of the conveying mechanism 1 changes or the type of material 100 changes, causing the second spraying trajectory 300 of the material 100 to change due to the guide mechanism 2, the angle and installation height of the magnetic suction component relative to the second spraying trajectory 300 can be adjusted to ensure that the material 100 is completely sprayed onto the surface of the magnetic suction component. This prevents the material 100 from falling onto the outside of the blade re-drying machine via the second spraying trajectory 300, thus avoiding waste of the material 100. The magnetic suction component can be a magnetic suction plate, and the area of ​​the magnetic suction plate is larger than the cross-sectional area of ​​the material 100 being sprayed.

[0034] Specifically, the mounting component is a universal hinge, which includes a ball joint and a magnetic connector connected to the ball joint. The height of the universal hinge on the external frame is adjustable. The magnetic connector's angle relative to the second spraying trajectory 300 is adjustable via the ball joint, and the angle adjustment of the ball joint is flexible. A guide rail is provided on the external frame, and the universal hinge is slidably connected within the guide rail. A limiter is provided on the guide rail to limit the height of the universal hinge, thus allowing for height adjustment of the universal hinge on the external frame, and consequently, adjustable installation height of the magnetic connector relative to the second spraying trajectory 300. The universal hinge and the external frame support can also be connected by clamps or clamping devices, which will not be elaborated further here.

[0035] Furthermore, the ball joint includes a ball head and a segmented ball socket. A magnetic element is fixedly connected to the ball head, and the ball head is slidably connected within the segmented ball socket. An elastic clamping ring is provided on the outer periphery of the segmented ball socket, which clamps the segmented ball socket to lock and limit the ball head. Locking and limiting the ball head restricts the movement of the magnetic element relative to the universal joint, preventing the magnetic element from shifting position during operation.

[0036] Optionally, the guiding mechanism 2 includes a roller and a roller bracket. The roller is rotatably connected to the roller bracket, which can be connected to an external frame. The roller bracket is oriented and externally adjustable on the external frame. The rotation of the roller on the roller bracket effectively disperses the material 100, and the rotating roller changes the throwing path of the material 100 to a second throwing trajectory 300. The oriented and externally adjustable roller bracket on the external frame allows for adjustment of the angle and installation height of the roller relative to the first throwing trajectory 200. When the conveying speed of the conveying mechanism 1 changes or the type of material 100 changes, causing the first throwing trajectory 200 of the material 100 to change from the discharge end 11, adjusting the angle and installation height of the roller relative to the first throwing trajectory 200 ensures that all the material 100 is thrown onto the surface of the roller, preventing the material 100 from falling onto the outside of the blade re-drying machine via the first throwing trajectory 200 and causing waste of the material 100. Specifically, bolts are threaded through the roller bracket, and a vertically extending groove is provided on the outer bracket. The roller bracket is connected to the groove by bolts. Loosening the bolts can adjust the angle and installation height of the roller bracket, and tightening the bolts can lock the roller bracket to the outer bracket.

[0037] Furthermore, the guiding mechanism 2 also includes a driving element configured to drive the roller to rotate, and the rotational speed of the driving element is adjustable. By adjusting the rotational speed of the driving element, the rotational speed of the roller is adjusted to adapt to changes in the conveying speed of the conveying mechanism 1 or changes in the type of material 100, thereby controlling the second sprinkling trajectory 300 within a certain range. Exemplarily, the driving element can be an electric motor, a pneumatic motor, or a hydraulic motor.

[0038] In this embodiment, an adhesive layer is provided on the surface of the roller, and multiple micro-hook-like structures are provided on the surface of the adhesive layer. The multiple micro-hook-like structures are distributed in an array on the surface of the adhesive layer. The adhesive layer structure is similar to the hook side of Velcro in daily life. When the material 100 is thrown onto the roller, the multiple micro-hook-like structures can adhere the hemp fibers or other filamentous impurities in the material 100, further improving the purity of the material 100.

[0039] Furthermore, a dynamic cleaning assembly is installed on the roller support. This assembly includes a rotating brush and a negative pressure suction nozzle. The rotating brush contacts the roller surface and rotates in the opposite direction to the roller. The negative pressure suction nozzle is located below the rotating brush and can be connected to an external dust removal device. The rotating brush effectively removes filamentous impurities adhering to the roller's adhesive layer, while the negative pressure suction nozzle draws these impurities from the rotating brush and transports them to the external dust removal device. This dynamic cleaning assembly effectively removes filamentous impurities adhering to the roller surface, reducing the workload for workers.

[0040] Optionally, the blade re-drying machine also includes an air separation mechanism, which is located within the spraying area of ​​the third spraying trajectory 400. By setting up the air separation mechanism, the material 100 can be separated into material piles of different masses by utilizing the differences in density, size, and shape of the material 100. The air separation mechanism can also effectively remove non-metallic impurities such as dust and debris from the material 100, further improving the purity of the material 100.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
